Carbide cutting tool question

A question for you guys that do use carbide tools. Is it easier to use a square shank tool that lays flat on the tool rest or a round shank that to me would tend to tip??
thanks in advance, Geo.

Square shank is more for peeling and scraping type cuts. With the round shanks, they are made so you can go to a shear/slicing angle for cleaner cuts, especially in bowl grain orientation.

If i,m cutting into an endgrain situation  like in a salt box bottom, would you go with the round shank? I want to purchase just one carbide tool to try this compared to the hss gouge that i'm using now. Really hard to cut an end grain bottom in this IPE wood.

I have the square shaft tools and I tilt the tools on purpose to get a shear cut. I have also attached a small level on the shaft to help keep the tool level. I don't know why I can't keep it level but I do.

I have the EasyWood Rougher and Finisher and both are square stock.  I tilted them for years and that worked fine.  On a pen turning forum, I heard about a carbide tool called the Magical Skew.  I researched it and decided I wanted to try one.  The bottom of the took is not flat, it is 30 degrees off flat on each side, making the bottom 120 degrees.  This gives 2 flat surfaces to work from that enables you to present the tool like a skew instead of a scraper.  I'm very happy with it.  I get smoother cuts from it than I do my skew.  I use it like a skew, though rather than like a bowl gouge. 

I use my Easy Rougher and Finisher - in addition to other tools when doing bowls  I can't see this tool for bowl turning.

Here's a link.  This is for the short handle model.  It also comes with a lnger handle which I ordered.

Not sure when this tool became available but I've often wondered who was going to be the first to knock of the bottom corners on a square shafted carbide scraper.
